Explanation: Yes, but have you ever experienced the Eagle Nebula with your ears ? The famous nebula, M16, is best known for the feast it gives your eyes, highlighting bright young stars forming deep inside dark towering structures. These light-years long columns of cold gas and dust are some 6,500 light-years distant toward the constellation of the Serpent (Serpens). Sculpted and eroded by the energetic ultraviolet light and powerful winds from M16’s cluster of massive stars, the cosmic pillars themselves are destined for destruction. But the turbulent environment of star formation within M16, whose spectacular details are captured in this combined Hubble (visible) and Chandra (X-ray) image, is likely similar to the environment that formed our own Sun. In the featured video, listen for stars and dust sounding off as the line of sonification moves left to right, with vertical position determining pitch.

说明: 你曾用耳朵去聆赏鹰状星云吗？ M16这个著名的星云，通常是以视觉上的享宴著称，其内有形成于高耸黝黑云柱深处的明亮年轻恒星。这些长达数光年的冰冷气体和尘埃柱，则位在巨蛇座方向约6,500光年远之处。而在M16星团大质量恒星的高能紫外星光和强烈恒星风的雕塑和侵蚀下，这些宇宙云柱难逃毁灭的宿命。这幅整合哈伯望远镜（可见光）和钱德拉望远镜（X射线）观测资料的影像，细致的呈现M16内恒星形成活动造成的湍动环境，而我们的太阳当年可能也是形成于类似的环境里。在这部主题影片里，请跟随由左向右移动的声化线，倾听恒星和尘埃美妙的唱和，在其中，天体的垂直​​位置决定音调的高低。
